The Effect of Medicare Accountable Care Organizations on Early and Late Payments for Cardiovascular Disease Episodes.
Article in Circulation. Cardiovascular quality and outcomes, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundInitial evaluations of the Pioneer and Shared Savings Programs have shown modest savings associated with care receipt in a Medicare accountable care organization (ACO). Whether these savings are affected by disease chronicity and the mechanisms through which they occur are unclear. In this context, we examined the association between Medicare ACO implementation and episode spending for 2 different cardiovascular conditions. METHODS AND
resultsWe analyzed a 20% sample of national Medicare data, identifying fee-for-service beneficiaries aged ≥65 years admitted for acute myocardial infarction (AMI) or congestive heart failure (CHF) between January 2010 and October 2014. We distinguished admissions to hospitals participating in a Medicare ACO from those to hospitals that were not. We calculated 365-day, price-standardized episode spending made on behalf of these beneficiaries, differentiating between early (index admission to 90 days postdischarge) and late payments (91-365 days postdischarge). Using an interrupted time series design, we fit longitudinal multivariable models to estimate the association between hospital ACO participation and episode spending. Our study included 153 476 beneficiaries admitted for AMI to 401 ACO participating hospitals and 2597 nonparticipating hospitals and 260 420 beneficiaries admitted for CHF to 412 ACO participating hospitals and 2796 nonparticipating hospitals. On multivariable analysis, admission to an ACO participating hospital was not associated with changes in early episode spending (AMI, $95 per beneficiary; 95% CI, -$481 to $671; CHF, $158; 95% CI, -$290 to $605). However, it was associated with significant reductions in late episode spending for both cohorts (AMI, -$680; 95% CI, -$1348 to -$11; CHF, -$889; 95% CI, -$1465 to -$313).
conclusionsFor beneficiaries with AMI or CHF, admission to ACO participating hospitals was not associated with changes in early episode spending, but it was associated with significant savings during the late episode. ACO effects on late episode spending may complement other value-based payment reforms that target the early episode.
